Application filed anuary 21, 1915. Serial No. 3,434.

erence being had to the accompanying drawings, which form apart of thisspecification.

My invention relates to internal combus? tion engines and an object ofmy improvement is to provide an engine of improved constructionparticularly inreferen'ce to ap-" pearance, compactness, convenience ofas-.

sembling, and accessibility.

In the accompanying drawings: Figure 1, is a central longitudinalsectional elevation of an engine embodying my invention. Fig. 2, is asection on the line B--B Fig. 1, looking from the left of said line.

Fig. 3, is an end elevation, the bottom being removed and various partsseparated, to illustrate the construction and mode of assembly. Fig. 4,is a side elevation showing the main casting of the frame and one of thecylinder castings and attached parts separated from the frame. Fig. 5,1s a section on the line E-E Fig. 1 looking from the left of saidline..-

a a indicates the engine casing as a whole, and b b is the frame or maincasting to which the other parts of the casing are secured.

c is the bottom, or oil pan, of the caslng.

d is a cover extending over the portion of the frame between thecylinder casting and inclosing part of the mechanism.

e is a housingor extension from the easing 1) which extends over the flywheel 40 and is-extended laterally to form lugs, or supports, it h forthe engine.

f is a casing at one end of the frame or casting b inclosing some of themechanism of the engine.

g, g indicate a pair of lateral extenslons at one end of the casting 6,serving as lugs to support the engine at this end while the lugs h itabove described support the engine at the other end.

2' j is are upwardly extending partitions formedintegral with the frameor casting b.

n is a web formed in the arc of a circle in cross section, as shown inFigs. 2 and 5 and extending between the lower ends of the end partitions2' and is.

0 p are end, and m m are side, walls integral with the casting b andforming the vertical walls of the crank case below the web n. m is acentral partition extending downward from the central part of the web11. and formed integral with the side walls of the crank case.

q, r and s are bearings formed respectively in the partitions 11, jfandla, the bearing g is adapted to 'receive and hold the dynamo 18 and thebearings 1' and s are adapted to receive the arbors' of the shaft 16which rotates therein. 1

t u 'v are bearings formed,.respectively,

in the end wall 0, the central'wall 'm and-the end wall of the crankcase. The main shaft 11 rests and is adapted to turn in the bearings t uu.

w a: 3 are bearings in the upper ends of, the partitions 2', j, 70 inwhich bearings the cam shaft 19 rotates. The main frame I) b is a singleintegral aluminum casting and it is faced off along its lower edges 2,3, along the upper edges of the side walls m m at 4, along the .tops ofthe partitions i j is and along the edges of said partitions asindicated at 7 and 8.

15, is a fan upon the shaft 16.

20, is a chain extending over sprocket wheels on the shaft 16 and on thecam shaft 19. The sprocket wheels uniting the shafts 11, 16 and 20 areof such relative diameters and so arranged that the cam 19 shall havethe proper angular position and speed of rotation relative to the shaft11.

22-22 are iron castings in which are formed the cylinders 21, the coredout water passages 3637, the intakemanifold 29, the intake ports 28, theexhaust valve ports 32 and the exhaust passages 30.

The cylinders 21 are formed in angular positions shown and are open attheir upper The castings 22 are machined along a surface 22. which is atthe angle shown to the axis of the cylinders 21,

e the cylinders open at their upper ends through such surface, and thevalve ports 28-32 are directly opposite the openings through thesesurfaces so that when the covers to the cylinder are removed the valvesand valve seats are easily accessible.

25, indicates covers, cored out for water passages as shown and providedwith screw threaded apertures 29 to receive the spark plugs. The covers25 fit against the surface 22* and are bolted thereto to cover thecylinders. The castings 2222 are finished off along their faces 23-24 atright angles to each other and fit against the side edges of theupwardly extending partitions z j Z and the uppbr edges 4 of the sidewalls m and the upper edges of the end walls 0 p and are secured in thisposition by bolts, as shown in Figs. 2 and 26-26 are the valves, thestems of Which extend inwardly toward each other and are acted on by thecams on the shaft 19, as indicated most distinctly in Fig. 2. This valveconstruction is particularly described and claimed in a copendingapplication filed January 21, 1915, Serial No. 3435 of 1915.

The exhaust passages 30 open through the flat horizontal uppersurfacesof the casting 2222 and cast aluminum manifolds 2727 are secured bybolts on said surface so that the passages 30 shall open into saidmanifold. The bottom, or oil, pan 0 is secured to the lower edges 2, 3of the walls m and together with said walls form the inclosed crankcase.An air pump may be mounted upon the front of the frame I; as shown andmeans provided to removably couple said pump to the shaft 19.
